Word Spinner enables you to create multiple but different versions of the same article, each of which can be submitted to a different article directory. It's a simple but powerful program. Look at the screenshot below.
Load an article into Word Spinner - it should be a text file - by clicking on File in the main menu, then Open and then navigating to where it is located...or open the article in your favourite text editor. Drag your mouse and Highlight the article text, right click and then copy to the clipboard. Go to File in the main menu, then Paste. The file should be transferred from the clipboard to Word Spinner. Save it as something meaningful by going to File and then Save.
Notice the small window in the image above? That's the Rewrite Manager, which you'll use constantly while setting the article up ready for spinning. Access it via the main menu by clicking Manager | Rewrite Manager | Open Rewrite Manager. The Rewrite Manager window will always stay visible - unless you click the Little Red Button with the cross to dismiss it.
